Efficient Enantiomeric Selectivity Separation Via Homochiral Graphene Oxide Membrane

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A new type of chiral graphene oxide (GO) membrane is proposed that exhibits a separation factor of up to 20.1 as well as a preferential enantiomer flux of 4.5 mmol m−2 h−1. Moreover, the only first FPLC‐compatible column has been further developed via stacking these chiral GO membranes.

Neural Network–Assisted Metasurface Retroreflector With Wide‐Angle Adaptivity

open access: yesElectron, EarlyView.
This work proposes a wide‐angle, multi‐polarization, self‐sensing, and self‐adaptive intelligent metasurface retroreflector, with a planar profile and ultrathin thickness. By integrating a pre‐trained artificial neural network (ANN), the metasurface retroreflector can recognize the incident angle and promptly adapt to changes in the incoming wave.

Bipolar photovoltaic effect in InSe/MoO3 van der Waals heterostructure for spontaneous light polarization detection

open access: yesInfoMat, EarlyView.
Bidirectional photo response in a two‐dimensional heterojunction photodetector controlled by light wavelength and polarization. Abstract Polarization is one of the most fundamental properties of light. Traditional polarization‐sensitive photodetectors, however, are limited in their ability to fully extract this information, as they translate the two ...
